UNITED .STATES PATENT OFFICE! IMPROVEMENT IN GANG-FLOWS.

Specification forming part of Letters Patent No. 37,750,dated February24, 1863.-

To all whom t may concern.:

Be it known that I, JACOB HAEGE, of Shi-k v loh, inthe county of St.Clair and State of Illinois, have invented a new and Improved Gang-Plow; and I do hereby declare that the following is a full, clear, andexact description of the same, reference being had to the accompanyingdrawings, making a part of this specilication, in which- Figure 1 is aside sectional view of my invention, taken in the line m a', Fig. 2;Fig. 2, a plan or top view of the same, a portion being in section, asindicated by the line x', Fig. 6; Fig. 3, a detached side view of a beamprovided with four plows for deep tillage; Fig. 4, a detached view of abeam provided'with a vsingle plow; Fig. 5, a back view of Fig. 4; Fig.

6, a sectional view of Fig. 2, taken in the line yy; Fig. 7, a detachedsectional view of a nutbOX;

This invention relates to an improved gangplow designed more especiallyfor western or prairie use.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents an axle, which is formed of two perforated bars, a a,placed one over the other, and having annpright frame, B, formed of twobars, b b, attached to each end of it. To the upper ends of the frames BB the driver-s seat .C is attached. The ends of the bars a a., whichform the axle A, are connected by uprights or standards c c, in whichvertical dovet'ail grooves d are made to receive dovet-ail projectionse, which have platcsf attached totheir outer surfaces, said plateshaving the arms a* of the wheels D D secured to them. (See moreparticularly Fig. 6.) To each plate f thelower end of a vertical rod, E,is attached. These rods E extend up through the seat C near its ends,and have screw-threads cut on them on which nuts g are fitted. Byturning these nuts it will be seen that the axle A may be raised orlowered, and the plows which are attached to the machine may be made topenetrate a greater or less distance into the earth. This feature of theinvention will'be fully unv derstood by referring to Fig. 6.

F represents the draft-pole, which is forked or of V form, andpermanently attached to the Figs. 1 and 2.)

axle A; and G G represent two curved arms,

lthe upper ends of which are attached by pivot-bolts h h to the frontand lower parts of the frames B B. The lower ends ofthe arms G G areconnected by a screw-shaft, H, on which three circular cutters, I I I,are placed and secured in proper position by jam-nuts i. (See (at leastthat would be the preferable material,) and they work on the surface ofthe ground, just in front of t-he axle A, as shown in Fig. 1. To thedraft-pole F there are secured two uprghts,jj, the upper ends of whichare connected bya curved bar, k. These uprights are .braced from theframes B B by bars Z l, both of which are shown in Fig. 2.

J represents a treadle or lever, whichis suspended from the back part ofthe seat C by two rods, m m, which are attached. to the seat by means ofhooks a n, so that they may swing freely. (See Fig. 1.) The treadle orlever J is of V form, and it has a bar, o, attached to its back part atright angles, and a foot-piece, p, is attached to it near its front end.

K, Figs. 1 and 2, represents a plow-beam, which is constructed of Woodand of two longitudinal parts, q q, with blocks r placed between' them,through which and the parts q bolts-s pass. To the back part of thisbeam K an inclined standard, L, is attached by a pivot-bolt, t, and saidstandard has the lower part of a rod, M, passing loosely through it. Theupper end of this rod M has a screw-thread cut on it, on which a nut, a,is fitted. This nut u is placedin a box, N, which is'formed of twoparts, n o, and the box is provided with trunnions w w, which are fittedin suitable bearings, a a', attached to the beam. (See Fig. 7.) To thelower end ofthe standard L a plow,0, is attached, and the lower endofthe rod M is connected by a pivot, b', with the landside P thereof.(See Fig. l.)

From the above description it will be seen that by turning the nut u thepoint of the plow O may be raised and lowered as desired, to regulatethc depth ofthe penetration thereof in the soil; and in consequence ofhaving the nut-box N hung on trunnions w w, as described, the latter andalso nut u are allowed to adjust themselves in line with the rod M asthe latter is raised or lowered under the ac- These cutters may be ofsteel,

tion oi the nut, and the former cannot in consequence be bent out of astraight or right line, as would be the case if the rod M passed througha rigid guide or bearing. The box N also serves as an oil-box and keepsthe screw of rod M well lubricated. The beam K passes over the bar o atthe back part of the treadle or lever J, and the front end of the beamis f1tted in a metal stirrup or loop, Q, which is at tached by a hook,c', to a double-tree, R, the latter being connected to the draft-pole F.

S is a vertical pin, the lower part of which is of cylindrical form, andis fitted in the perforations of the parts a a of the axle A. The upperpart of this pin is of dat form, and'is fitted between the two parts g gof the beam K. Io the lower part of the pin S there are attached twochains, d d', and the ends of these chains are attached to the ends of asmall bar, T, which is connected to the beam K by a wooden pin, c.

As the machine is drawn along it will be seen that the driver can fromhis seat G elevate the plow at any time by simply treading on thetreadle or lever J, leaving the seat C, and allowing` his whole weightto bear on said treadle or lever, the curved bar 7c serving as a supportfor the driver when standing on the lever or treadle. The plow-beam, itwill be seen, is raised by the back part of the lever or treadle as thefront part of the same is depressed. WVhen the plow is in operation thestrain or pull is upon the Wooden pin 6'; and in case the plow comes incontact with any ob struction thatit cannot throw aside, the wooden pine will break and the beam will draw out from the stirrup or loop, Q,leaving the beam and plow detached from the axle A. The plow thereforecannot be broken or strained, nor any of the parts connected therewith.

Any numberot'plows may be attached to the beam K. In Fig. 3 four plows,UV W X, are shown attached to a beam, Y. This arrangement is designedfor deep tillage, U being a surface-plow, V WV deeper plows, and X asubsoil-plow. This latter plow, X, has its adjusting-bar Z, whichcorresponds to the rod M of plow O, made sharp at its front edge toserve as a cutter or colter,and it passes through a yoke, A, the frontend of which is secured by a pivot,f, to beam Y, and the back endsecured to the beam by a screwbolt, g.

To the lower part ofthe barZ and front part.' ofthe plow X there isattached a cutter, B. This cutter acts upon and divides roots, and isvery essential in deep tillage. In Figs. 4 and 5 a plow-beam, Gf, isrepresented with handles- C attached at their lower ends totthe beam bya pivot-bolt, g'. The handles are connected by a cross-bar, It', whichhas a box t" attached, in which a nut, i',is itted, and through whichnut a screw-rod,7o, passes, the lower end of the screw-rod being pivotedto the back part of the beam C', as shown at l. By turning the nut j thehandles C may be raised or lowered to suit the height of a man or boy.These handles are applied to the beam in case it should be necessary todetach the plow from the carriage at any time and use it separately.

The rotary cutters, I II, cut all stalks, weeds, trash, Src., which maylie in their path, and thereby greatly facilitate the work of the plows.These cutters, it will be seen, are allowed to rise and fall to conformto the irregularities of the surface of the ground, in consequence oftheir shaft H being placed in the arms G G, which are allowed to work ontheir pivots h, and by adjusting the jam-nuts t' the cutters may besecured at a greater or less distance apart, as may be desired. One ormore beams may be attached to the axle A, as the nature'of the work mayrequire.

I do not claim in this specication the box N, hung on trunnionsw w, andcontaining the nut u ot' the screw-rod M, for that feature forms thesubject-matter of another or separateapplieation.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, `is

.1. The attaching of the plowbeam to the axle A by means of the stirrupor loop Q, pin S, chains d d and bar T, and wooden pin e', incombination with the lever or treadle J all arranged as shown, wherebythe plow or plows may be readily raised above the surface of the groundwhen necessary, andthe beam allowed to become detached from the axle orcarriage when the former cornes in contact with any obstruction whichmay lie in their path.

2. The rotary cutters I, when placed on a screw rod or shaft H, andsecured thereon by jam-nuts t', and said shaft hungin the arms G G,substantially as and for the purpose specitied.

3. The combination of the bar Z, and cutter B', when applied to thesubsoil-plow X, and used in connection with a gang-plow, for the purposeset forth.
